Serial port

guipru

Hello,
I try to send 1 byte via serial port using inline_script (python). I would to trigger this script after keyboard response and only for specific stimuli. So, I place a "run if" [var]="yes" associated with another variable in the first sketchpad.
I have a first script in the beginning of my experiment

import serial
ser = serial.Serial ("COM5", 9600)

And my second script, after keyboard response is :

ser.write ('0')
print (ser)
ser.close

The most minimalist codes of the world! But when I launch opensesame, it cratches only when stimuli associated by var "yes" arrive.
Do you have ideas my friends?

I specify: crach arrive after 3 presentations...

Hi guipru,

You can't use a variable named var as var is the name of the variable object.

• http://osdoc.cogsci.nl/3.1/manual/variables/#using-variables-in-python

So you could use and inline with var.somename='yes' and a Run if with [somename]='yes' for example.

Hope this helps.

Best,
Jarik
